RAILROAD-TIE.

To all 'whom t may concern.'

Be it known that I, VVILLTAM ToMLINsoN, a subject of the King of England, residing at St. Catherines, in the Province of On tario and Dominion of Canada,'have invented new and useful Improvements in Railroad-Ties, of which the following is a specication.

The invention is designed to provide a new and improved form of railroad'tie formed with a steel outer covering and a concrete interior whereby the most effective construction for strength and length of Service is obtained. It is further designed to provide a device of this cliaracterrin which unique means is provided for the attachment of the rails to the tie. Y l

To the exact construction in which it is shown and described, the invention is not to be restricted. The right isreserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or"alterations are comprchended in spirit, by the annexed claim.

In the accompanying drawings:

Figure l is a top plan view of the tie, sections of track rails being. shown attached thereto.

F ig. 2 is a bottom plan view.

Fig. 3 is a section on the line 3 3 of Fig. 1. K

Fig. 4 is a section on the line 4--4 of Fig. l.

s shown in the drawings, the tie is formed by providing two longitudinal channel members l which form the two sides of the tie respectively. Lattice bars 2 Ydiagonally disposed unite the two channel members at the bottom in such a manner that the two stand in spaced relation to each other with their flanges facing. The lattice bars are riveted or otherwise suitably attached to the bottom flanges.

The two channel members are provided on the top with plates 3 which are riveted or otherwise suitably secured to the top flanges and these plates together with a hinged cover 4 constitute thetop covering of the tie. The two plates 3 have their facing ends spaced apart and the cover` 4 serves to cover this portion of the tie between the two facing ends of these plates. The cover is hingedly mounted to one of the channel Specification of Letters Patent.

members 1 by means of hingesV 5 and in transverse section, it is channel Shaped, so that the flanges of the channel may overlie the two channel members l. The cover 4 while being hingedly mounted to one chan nel member l, when in closed position is Secured against opening by means of ypad lock 6 and the necessary attendant devices to permit the lock to secure the cover against opening. The space between the two channel members and below the plates 3 and cover 4 is filled with concrete or cement 7 and in this concrete are set the heads of bolts 8, the Shanks of which project through the y Patented June 29, 1920.

plates 3 so that they 4may receive the rail supporting brackets 9 which abut the rails l() on either side, the brackets being of Such conformation that they lie againstthe upper face of the rail flange against the rail web and against the under face of the tread.

The provision of the door or cover 4 provides for the pouring in of the concrete after the steel work of the tie has been set up and if the ballast for the tie be crushed stone, the concrete will unite therewith and when set will provide a firm mounting for the tie. The cover 4 overlaps the adjacent ends of the two plates 3 and its [langes overhang the Vtwo channel members '1, thus serving to eX- member and covering the space between the plates, means for securing the cover in closed position, a filling material in the space between the channels and below the plates and cover, and means detach-ably mounted upon the plates for securing railroad rails thereto.

In testimony whereof I afliX my signature.

WILLIAM TOMLIN SON.
